1.闹铃activity

package com.example.myalarm;

import java.util.Calendar;

import java.util.Date;

import java.util.Locale;

import android.media.RingtoneManager;

import android.net.Uri;

import android.os.Bundle;

import android.provider.MediaStore;

import android.app.Activity;

import android.app.AlarmManager;

import android.app.PendingIntent;

import android.app.TimePickerDialog;

import android.app.TimePickerDialog.OnTimeSetListener;

import android.content.Intent;

import android.database.Cursor;

import android.util.Log;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.TimePicker;

public class AlarmActivity extends Activity {

private static final String TAG = "AlarmActivity";

AlarmManager alarmManager;

Calendar calendar = Calendar.getInstance(Locale.CHINESE);

Button setTime;

Button setRing;

Button setOver;

Uri ringUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_alarm);

alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

setTime = (Button) findViewById(R.id.setTime);

setRing = (Button) findViewById(R.id.setRing);

setOver = (Button) findViewById(R.id.setOver);

//setTime();

//setRingtone();

setTimeAndRing();

}

private void setTimeAndRing(){

setTime.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View view) {

setTime();

}

});

setRing.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View view) {

setRingtone();

}

});

setOver.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View view) {

setAlarm(calendar);

}

});

}

//启动闹玲，设置闹玲

private void setAlarm(Calendar calendar){

Intent intent = new Intent();

intent.setClass(this, AlarmBroadcastReceiver.class);

intent.putExtra("msg", "Get up!Get up!");

intent.putExtra("ringURI", ringUri.toString());

Log.d(TAG, ringUri.toString());

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

alarmManager.set(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(), pendingIntent);

}

//设置时间

private void setTime(){

Date date = new Date();

calendar.setTime(date);

int hour = calendar.get(Calendar.HOUR);

int minute = calendar.get(Calendar.MINUTE);

new TimePickerDialog(this, new OnTimeSetListener() {

@Override

public void onTimeSet(TimePicker timePicker, int hour, int minute) {

calendar.set(Calendar.HOUR,hour);

calendar.set(Calendar.MINUTE,minute);

}

}, hour, minute, true).show();

}

//设置闹玲铃声

private void setRingtone(){

Intent intent = new Intent();

intent.setAction(RingtoneManager.ACTION_RINGTONE_PICKER);

intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, false);

intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "设置闹玲铃声");

intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_ALL);

Uri pickedUri = RingtoneManager.getActualDefaultRingtoneUri(this,RingtoneManager.TYPE_ALARM);

if (pickedUri!=null) {

intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI,pickedUri);

ringUri = pickedUri;

}

startActivityForResult(intent, 1);

}

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);

if (resultCode!=RESULT_OK) {

return;

}

switch (requestCode) {

case 1:

//获取选中的铃声的URI

Uri pickedURI = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);

Log.i(TAG,pickedURI.toString());

RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALARM, pickedURI);

getName(RingtoneManager.TYPE_ALARM);

break;

default:

break;

}

}

private void getName(int type){

Uri pickedUri = RingtoneManager.getActualDefaultRingtoneUri(this, type);

Log.i(TAG,pickedUri.toString());

Cursor cursor = this.getContentResolver().query(pickedUri, new String[]{MediaStore.Audio.Media.TITLE}, null, null, null);

if (cursor!=null) {

if (cursor.moveToFirst()) {

String ring_name = cursor.getString(0);

Log.i(TAG,ring_name);

String[] c = cursor.getColumnNames();

for (String string : c) {

Log.i(TAG,string);

}

}

cursor.close();

}

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

getMenuInflater().inflate(R.menu.alarm, menu);

return true;

}

}

2，布局文件

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

>

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="设置时间"/>

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_below="@+id/setTime"

android:text="设置铃声"/>

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_below="@+id/setRing"

android:text="设置完成"/>

3.广播接收闹铃信息：

package com.example.myalarm;

import java.io.IOException;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.media.MediaPlayer;

import android.net.Uri;

import android.util.Log;

import android.widget.Toast;

public class AlarmBroadcastReceiver extends BroadcastReceiver {

Uri ringUri;

@Override

public void onReceive(Context context, Intent intent) {

String msg = intent.getStringExtra("msg");

Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();

MediaPlayer mp = new MediaPlayer();

String uri = intent.getStringExtra("ringURI");

if (uri!=null) {

ringUri = Uri.parse(uri);

Log.d("AlarmActivity", ringUri.toString());

}

try {

mp.setDataSource(context, ringUri);

mp.prepare();

} catch (IllegalArgumentException e) {

e.printStackTrace();

} catch (SecurityException e) {

e.printStackTrace();

} catch (IllegalStateException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

mp.start();

}

}

4.在manifest文件中注册广播

以上代码就是实现Android闹钟的全部代码了，希望大家能够喜欢。
